4 Claims. (Cl. 261-23) The present invention relates to an air cleaner and moistener for carburetors and it consists in the combinations, constructions and arrangements of parts herein described and claimed.

Generally there is provided a device which is attachable to the upper end portion of a conventional radiator of the engine of an automobile or the like. The device comprises a casing having an intake connection from the water pump of the engine, an outlet connection to the carburetor of the engine and a pair of air inlets. Novel means is provided within the casing for directing water from the Water pump downwardly in a plurality of divergent streams to a plurality of novel tubular members which act to maintain a water level in the lower end of the casing and also to admix air with the Water returning to the conventional radiator core. This latter action acts to not only wash the air but further acts to assist in keeping the engine cool and to thus return to the casing from the conventional water pump thoroughly cleaned and moistened air which is then directed by novel means to the carburetor outlet. By thus furnishing thoroughly cleaned and moistend air to the carburetor, there will result a greater efliciency in the engine as well as a longer life therefor and .an appreciable saving in fuel costs.

It is accordingly an object of the invention to provide a device of the character set forth having novel means for delivering to the engine of an automobile or the like cleaned and moistened air for the carburetor thereof.

Another object of the invention is to provide a device of the character set forth which is comparatively simple in construction, relatively inexpensive to manufacture and yet effective and eflicient in use.

Still a further object of the invention is to provide, in a device of the character ;et forth, novel means for admixing air with the water in a conventional radiator.

Other and further objects of the invention become apparent from a reading of the following specification taken in conjunction with the drawings, in which:

Figure 2 is a front elevational view thereof,

Referring more particularly to the drawings, there is shown therein a device of the character set forth comprising a horizontal base plate 10 of generally rectangular shape to which is afiixed a forward wall 11 and a rear wall 12 of generally semi-circular shape and having their rounded sides presented upwardly. The casing is completed by an arcuate cover 13 which interconnects the rounded edge portions of the front and rear walls 11 and 12. The base plate 10 interconnects the lower portions of the top 13 and the front and rear walls 11 and 12 in upwardly spaced relation to the lower edges thereof thus providing a flange 14 therebelow.

An arcuate plate 16 having a plurality of perforations 17 therethrough extends transversely through the casing approximately centrally thereof with its convex face presented upwardly and fully interconnects the inner faces of the top 13 and the walls 11 and 12.

A pair of air inlet pipes 18, laterally spaced from each other, extends from the front wall 11 rearwardly and downwardly through the plate 16, each terminating immediately therebelow and each is provided at its forward end with a screen 19.

A fitting 20 is centrally positioned in the upper portion of the rear wall 12 and has 'afiixed thereon by means of a clamp '21 one end of a hose 22 which leads to a carburetor (not shown). An 'arouate plate 23 presenting its concave side upwardly, interconnects the front and rear walls 10 and 11 and is connected at each of its :ends to upper portions of the inner face of the top 13 providing therewith an upper compartment generally indicated at 24. The top 13 is provided with a plu rality of openings 25. A 'bafiie plate 26 extends from the rear wall 12 immediately below the plate 23 forwardly and downwardly to the front wall 12 between the pipes 18 and is provided at either side with wing portions 27 which extend laterally between the pipes 18 and the forward wall 11. The plates 16 and 23 together with the top 13 and front and rear walls together form a compartment generally designated at 28.

A rearwardly and downwardly extending fitting 29 is mounted in the rear wall 12 and connects with the compartment 28 and to its free end there is aflixed one end of a hose 30 by means of a clamp 31, the end of the hose 30 being connected to the water pump (not shown) of an engine.

Extending upwardly from the base plate- 10 is a plurality of tubular members each generally designated at 32 and which members are shown in greater detail in Figures 9 and 10. The members 32 are preferably and as shown arranged in a plurality of forwardly and rearwardly extending rows. Each of the members 32 extends through the plate 10 and has its lower edge lying in the same plane as the lower face of the plate 10. Each of the members 32 is of inverted U-shape and pro vided with a relatively long leg 33 attached, as aforesaid, to the plate 10 and a relatively short leg 34. The longer leg 33 in each case is provided with a not-ch having a horizontal side 35 and an angula-rly and upwardly extending side 36, the notch being designated generally at 37. A rearwardly .and upwardly extending filler neck 38 is mounted in the lower portion of one side of the rear wall 12 and has positioned therein an overflow pipe 39 which extends therethrough and downwardly alongside a radiator core upon which the present device is mounted. The upper end of the drain pipe 39 is in the same plane as the horizontal portions 35 of the notches 37. The plate 16 forms with the base plate 10, front and rear walls 11 and 12 and top 13, a compartment which is generally designated at 40.

At 41 there is generally designated a conventional radiator core having a lower chamber 42 provided with a lit-ting 43 in the lower end thereof whereby a hose 43a 3 1 leading to the-water jacket of an engine may be conected an. upset. chamber Ki li?! if. @1195 L5.
